Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A use of get request method with sensitive query strings vulnerability in volume encryption of Synology Storage Manager package before 1.0.1-1100 allows local users on Windows to obtain sensitive information.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The vulnerability exists in the volume encryption feature of Synology Storage Manager package where sensitive query strings are transmitted via GET requests instead of secure methods. This allows local Windows users to potentially capture sensitive information through browser history, server logs, or network interception.

MitigationUpgrade Synology Storage Manager to version 1.0.1-1100 or later to remediate the vulnerability. As a temporary measure, restrict local user access and monitor for suspicious access patterns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Synology Storage Manager is installed
    Access the Synology DSM Package Center and check if 'Storage Manager' is listed among installed packages, or run 'dpkg -l | grep synology-storage-manager' via SSH if the package manager is accessible
    Affected if Storage Manager package is not present in the package list
  2. Determine installed Storage Manager version
    In DSM Package Center, click on Storage Manager and view the version information displayed, or check via command line with 'cat /var/packages/synology-storage-manager/INFO' or similar package metadata file
    Affected if The version shown is less than 1.0.1-1100 (e.g., 1.0.0-xxxx or any build below 1100)
  3. Check if volume encryption feature is in use
    Open Storage Manager application and navigate to the volume management section to see if any volumes have encryption enabled, or inspect configuration files in /volumeX/etc/ (where X is the volume number) for encryption settings
    Affected if Any volume has encryption enabled and the Storage Manager version is below 1.0.1-1100
  4. Review HTTP access logs for sensitive query strings
    Examine Synology web server access logs (typically in /var/log/nginx/ or /var/log/httpd/) for GET requests to Storage Manager API endpoints containing sensitive parameters like passwords, keys, or encryption-related query strings
    Affected if GET requests with sensitive-looking parameters (password, key, encryption, token) are logged in web server or reverse proxy logs

You are affected if Synology Storage Manager is installed with a version below 1.0.1-1100 AND the volume encryption feature is being used, exposing sensitive query strings in browser history, logs, or network traffic.
